Abstract

This work aimed to obtain information seeking the characterization of the anaerobic digestion of three poultry litter kinds (elephant grass, elephant grass + wood shavings and wood shavings) obtained after one broiler breeding cycle and after reuse in a second broiler breeding cycle. Results showed the three kinds of poultry litter didn’t interpose in the total volatile reduction. Concern about biogas production obtained greatest values with poultry litter from elephant grass. The poultry litter reuse showed important, promoting advantageous in biogas production parameters, independent from kind of poultry litter used.
